Specification of Letters Eatent.

Application filed February 18, 1915. Serial No. 9,010. i

To all whom it may concern: i

Be it known that I, HARRY H. SGHROYER,

a citizen of the United States, and a resi-- dent of the city 'ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in leather-Strips forCar-VVindows;.and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing's, and to the numerals .of reference markedthereon, which form a part of this specification.-

This invention relates to weather stripping for car windows, and has forits object to provide certain improvements in the construction disclosedin Letters Patent No.

. 1,094,481, granted April 28, 1914, to the Acme Supply Co., as myassignee.

This object I accomplish in the manner and by the means hereinafterdescribed and claimed, reference being had to the accompanying drawing,in which Figure 1 is a fragmentary exterior view of a car illustrating awindow equipped with Weatherstripping means embodying the principles ofmy invention.

Fig. 2 is a fragmentary detail section taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary detail section taken on line 33 of Fig. 1,illustrating the sash in an elevated position.

Fig. 4 is a fragmentary exterior view of the lower corner of the windowconstruction with the sash in the position shown in Fig. 3.

Fig. 5 is an enlarged fragmentary detail sectfion taken through thelower rail of the sas Fig. 6 is a view similar to Fig. 3, illustratingthe sash in closed position.

As shown in the drawings:

In the adaptation of my invention herein illustrated, the frame for thesash forms .on the opposite side of said inwardly stamped portion 4, asimilar tracking memher 6, is formed. An outer cheek plate 7, of thewindow post is flanged around and secured to the exterior surface ofsaid tracking member 6, and extends inwardly-across the window frame anamount substantially equal to that of the inner stop 3, thus aflording aWeatherstripping outer side stop 8. The window sash itself consists ofside stiles 9, and top and bottom rails, of which the bottom rail isindicated by the reference numeral 10.

The outer surfaces of said stiles 9, of the sash are provided withstepped recesses, as clearly shown in Fig. 2, each to receive the stopor eatherstripping element 8, therein, and plates 11, are secured inflush relation upon the exterior of said stiles 9, and pro ject oversaid recesses, overlapping the elements 8, and thus sealing the same inthe pocket thus formed.

The sill of the window frame is formed of a sheet of metal 12, stampedto the re quired shape, and, as clearly shown in Figs. 3 and 6, the sillinclines downwardly on the exterior of the car. An inner sill 13,preferably of wood, is secured upon said sill member 12, in any suitablemanner, and

extends transversely across the window frame between the side membersthereof, so that the lower rail 10, of the sash when in a lowered orclosed position, as clearly shown in Figs. 1 and 6, abuts against theouter edge of said inner sill member 13, and rests upon the inclinedsurface of the sill member 12. The under surface of the rail 10-, of thewindow sash is inclined an amount corresponding to the inclination ofthat portion of the sill member 12, against which the window sash restswhen in closed position, and secured upon said under surface of saidrail 10, is a strip of metal 14, folded inwardly at its outer edge intoa suitable recess therefor, indicated by the reference numeral. 15, atthe outer edge of the rail, and at the inner edge of the rail curveddownwardly, as indicated by the reference numeral 13.

A sealing or Weatherstripping element, such as rubber or any othersuitable flexible material 17, is secured upon said metal plate 14, bymeans of a strip 18, which may be attached thereto by screws or othersuitable means. Said flexible material 17', as clearly shown in theenlarged view in Fig. 5, is attached along its central portion near theinner edge of the rail member so that the margins of said strip dependdownwardly and are normally inclined outwardly, the stiffness of thematerial itself serving to maintain the outer margin projected outwardlyand downwardly, and the curved portion 16, of the metal strip 14,serving to hold the inner margin normally in the position shownin Fig.5.

When the window sash is drawn upwardly to any of the various positionsillustrated in Figs. 1, 3 and 4:, the outer margins of the sealing strip17 at its ends track behind the fixed stop members 8 on the windowframe, thus springing said strip in-' wardly and preventing the samefrom retaining a set form or losing its resiliency. However when thesash is lowered, the strip will be forced outwardly and downwardly uponthe inclined sill member 12, and as the lower ends of said stops 8 arecut away,v

- leaving recesses 19 between the ends of the same and the surface ofthe sill 12, the ends of the strip 17 will be projected through saidrecesses 19 and will be pressed down upon said sill 12 by the lower endsof the plates 11 on the sash, as clearly seen in Fig. 6. At the sametime the inner margin of said sealing strip 17 is flexed outwardly andcompressed etween the strip .18 and the upper surface of the sill 12, asclearly shown in Fig. 6, thus afi'ording another line of seal for thesash when in closed position in the window frame.

I claim as my invention:

In a device of the class described, a window frame, a window sill, asash 'slidable in said frame, a resilient Weather stripping secured tothe underside of the sash and having an outer depending margin, outerside stop members secured to said frame and overlapping said sash andterminating slightly above the window sill to permit the projectiontherebeneath of the ends of said weather stripping when the sash islowered to its closed position, and plates on said sash overlapping saidstop membersand adapted when said sash is lowered, to press down uponthe sill the ends of said weather stripping projecting from beneath saidstop memers.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.
